SAO PAULO, Brazil (AP) _- A train derailed Thursday and crashed into another train, injuring at least 20 people, authorities said.
Some of the victims were hospitalized with serious injuries from the accident in Itaquaquecetuba, a small town near Sao Paulo, said police Officer Roberto Benite.

Police are investigating what caused one of the two passenger trains to derail and smash into the side of the second, oncoming train.

Authorities continued to comb the wreckage area late Thursday for more victims and possible fatalities, he said.
